Intensifying the lifetime of Wireless Sensor Network using a centralized energy accumulator node with RF energy transmission

Energy conservation in the field of Wireless Sensor Networks (WSN) is of a great concern to the modern day researchers which has lead to numerous research studies. However, irrespective of the various energy efficient routing protocol for WSN, the energy of a sensor node gets exhausted soon which in turn might lead to disastrous problems. To address this problem of energy depletion, a technique to intensify the sensor node energy is proposed. A centralized energy accumulator node will transmit the energy to the nearest nodes through intermediate hops using Energy Reconciling Medium Access Protocol (ERMAC) via radio frequency. Considering the unjustness, the protocol can efficiently adapt itself to power up the lifetime of sensor networks. The results through simulation show the stability of the wireless sensor network with ERMAC and the energy harvesting rate of a sensor node.
